Recently, BOE announced that it will launch the world’s first 55 inch 4K active matrix quantum dot light emitting diode (amqled) display screen, which is another significant progress in the field of electroluminescent quantum dots after the release of high-resolution qled technology at the beginning of this year. It is understood that quantum dot light-emitting diode (qled) is generally considered to be the next generation of display technology with more subversion after active matrix organic light-emitting diode (AMOLED).

At present, the application of quantum dot technology in display products mainly includes photoluminescent quantum dot backlight technology and active electroluminescent quantum dot diode technology (amqled).

Different from photoluminescence quantum dot backlight technology, amqled display can make quantum dots emit light without backlight, which has the advantages of self illumination, wide color gamut, long life and so on, and has become the development direction of quantum dot display.

Among them, the development of large-scale quantum dot printing technology and products is the key breakthrough point, which attracts the attention of the industry.

BOE’s 55 inch 4kamqled display product adopts electroluminescent quantum dot technology, with a resolution of 3840 × 2160, a color gamut of 119% NTSC, and a contrast ratio of 1000000:1. It has broad market space and application prospects in the field of large-scale display.

In the amqled field, BOE’s electroluminescent quantum dot technology is at the international leading level. As early as 2017, BOE launched a 5-inch, 14 inch amqled product prototype with full ink-jet printing process, which was highly praised by Sid bestinshow award.
